Abstract
The invention discloses a preparation method of a high-temperature resistant coating. The preparation method comprises the following technical steps of: uniformly mixing 10-15g of an epoxy resin, 2-4g of glass powder, 5-10g of a boron-containing phenolic resin, 6-10g of titanium dioxide, 5-10g of borax, 3-5g of silicon, 0-7g of talcum powder, 2-6g of sodium hydroxide, 0.5-1.5g of titanium nanometer slurry, 10-20g of cobalt oxide, 0-1.5g of organobentonite and 0.02g of an antifoaming agent, carrying out ball milling to disperse for 2 hours, adding water or water vapor at 80-100 DEG C to uniformly stir and mix, and adding a curing agent to cure for 1-2 hours so as to obtain the high-temperature resistant coating. Due to the introduction of boron, the high-temperature resistance of the coating is improved, and at the same time, the coating is wide in applicable temperature range, and can be cured at a lower temperature, so that the film-forming property of the coating is good, and the corrosion resistance is good.
Description
Technical field
The invention belongs to chemical field, relate to a kind of can be under the continuous high temperature condition coating and preparation method thereof of life-time service, be specifically related to a kind of high-temperature resistant coating and preparation method thereof.
Technical background
Boron bakelite resin is except having good acidproof, the alkaline resistance properties of general resol, its heat decomposition temperature can be up to 438 ℃, due to B-O bond energy (774.04 kJ/mol) higher than C-C bond energy (334.72 kJ/mol), therefore the thermotolerance of boron phenolic aldehyde cured article (the three-dimensional cross-linked reticulated structure that contains boron) and ablation resistance are far above common resol; In addition, the B-O key has again kindliness preferably, therefore the fragility of boron bakelite resin reduces, mechanical property increases, and is commonly used for tackiness agent, to improve the over-all properties of material.
Along with the develop rapidly of modern science technology, in the high-tech areas such as Aeronautics and Astronautics, electronics, machinery, the resistance toheat of coating there is more and more higher requirement.Some scientific research institutions also have fully certainly boron bakelite resin, and the heat decomposition temperature of boron bakelite resin can up to 438 ℃, have the coating that the boron phenolic aldehyde adds also can be widely used in the environment that contains sour gas and impurity under high temperature.
Summary of the invention
